 ### Keyword Interactions
 
-Keyword behavior MAY be defined in terms of the annotation results of
-[subschemas](#root) and/or adjacent keywords (keywords within the same schema
-object) and their subschemas. Such keywords MUST NOT result in a circular
-dependency. Keywords MAY modify their behavior based on the presence or absence
-of another keyword in the same [schema object](#schema-document).
+Unless otherwise specified, keywords act independently.
+
+Keywords MAY modify their behavior based on the presence, absence, or value of
+another keyword in the same schema object. Such keywords MUST NOT result in a
+circular dependency.
+
+Supplementary specifications are encouraged to specify any dependencies as part
+of the dependent keyword (i.e. the keyword whose behavior is modified).
+
+Within this document, keyword dependencies are expressed using one of the
+following mechanisms:
+
+- Static dependencies, in which the dependency relies on the presence or
+  contents of another keyword.
+- Dynamic dependencies, in which the dependency relies on the evaluation of
+  another keyword against an instance. This dependency may be on either the
+  annotations produced by the keyword or the validation result of its
+  subschema(s).
+
+These mechanisms are used merely to describe dependencies; they are for
+illustrative purposes and not prescriptive. Implementations MAY use whatever
+mechanisms make sense given the needs of their architecture and language in
+order to achieve the specified behaviors.
